Top 10 CSE Interview Questions for Freshers

To assist you in succeeding in your interview, we have compiled the most typical technical interview questions for CSE students and discussed the answers.

10 Questions You Should Learn While Undergoing Technical Interview Preparation for CSE

For freshmen and experienced candidates looking to land their ideal job, here are some sample CSE interview questions.

  • Point out some differences between C and C++

Here are some basic differences between C and C++

C programming

1. This language is procedurally oriented

2. C uses a top-down approach

3. A C program's file extension is .c

4. A large programme code is broken up into manageable chunks in the C programming language, which are known as functions

5. Function declaration is not a feature of C's structure

C++ Programming

1. It is a language for Object-Oriented Programming

2. C++ adopts a bottom-up approach to programming

3. A C+ + programme language's file extension is .cpp

4. A large program's code is separated into Objects and Classes in the C++ programming language

5. The C++ structure feature allows you to declare a function as a member function of the structure

  • How do you define SDLC?

The term "SDLC" (Systems Development Life Cycle) refers to designing, organising, implementing, and testing a system. It focuses on effectively producing a software product.

  • Mention a few well-known Computer Processors.

Some of the most well-liked computer CPUs include AMD Ryzen 5, AMD Ryzen 7, Intel Core i9, Intel Core i7 and Intel Core i5.

  • Where do you use the term "chipset"?

A chipset assists you in managing inter-device communication and is essential for assessing whether a computer system is operating effectively or not. It regulates communication between every element of the computer, including the RAM, storage, and CPU.

It informs you of the types and numbers of USB devices your motherboard can support. Chipsets primarily assist a computer system in managing peripheral devices, including the keyboard, monitor, mouse, and printer.

  • What kinds of access modifiers are there?

There are four different categories of access modifiers, as follows:

  • Evident in the complete bundle. No modifier is required.
  • Private - only the class can see it.
  • Public – can be seen by everyone.
  • Protected: visible to subclasses and packages.
  • What distinguishes overloading from overriding?

When two or more methods in the same class have the same method name but distinct parameters, this is known as overloading (i.e. different method signatures).

Overriding occurs when two methods with identical method names and parameters (i.e., method signature) are in a parent class and a child class, respectively.

  • What are machine learning and deep learning?

Machine learning is a technique where a system learns on its own by collecting relevant data without the help of a programmer.

Deep learning is a computer program that imitates the neuronal network in the brain. Deep learning is a branch of machine learning that uses deep neural networks, and it is referred to as such.

  • In Java, how does a character stream differ from a byte stream

The most popular method for 16-bit Unicode input and output is Java character stream. The primary classes used by users are FileReader and FileWriter, respectively, which internally use FileInputStream and FileOutputStream. 

The primary distinction is that FileReader and FileWriter read and write two bytes simultaneously.

Java Byte stream is mostly used for 8-bit Unicode input and output.

FileInputStream and FileOutputStream are the two main classes involved with byte streams.

  • What do we mean by abstract class?

A class is referred to be an abstract class if the abstract keyword appears in a declaration. 

The following are the properties of the abstract class:-

If a class has at least one abstract method, it must be designated abstract, even if abstract classes may or may not contain abstract methods. It is impossible to instantiate the abstract class.

We must inherit from another class in order to use an abstract class.

If we inherit an abstract class, we are obligated to implement each of its abstract methods.

  • What is inheritance?

In the field of computer science, we regularly employ inheritance as a part of programming. It speaks of the feature that a superclass imparts to a subclass.

This guide include most frequently asked computer science interview questions. Therefore, you can use this for you final preparation. If you have enough time you can also learn some additional technical interview questions for CSE freshers.

How to Prepare for Technical Interview for CSE?

How to Prepare for Technical Interview for CSE

Whenever you are approaching any interview panel, ensure following these below-mentioned measures for effective outcome:

  • Pay close attention to the questions asked during the practice sessions and ask any questions you have. Then begin to brainstorm, and it's always a good idea to rough out your ideas on paper so that people can see what you're doing. 
  • Additionally, be sure to frequently address the mock interviewer by outlining your approach to the topic and providing them with some context. If your strategy isn't working or meeting the requirements, adjust it immediately.
  • Get familiar with the format and kinds of questions. First, carefully read any materials the recruiter may have supplied you to help you prepare for the interview. 
  • Verify if the company's website contains resources for interview preparation. Ask the recruiter if you are unsure of the format.
  • Even if it’s a technical round, always be ready for traditional or behavioural questions as employers frequently complain that students were too focused on the technical interview to have prepared responses to standard inquiries like:

"Tell me about yourself?

or "What makes this job appealing to you?”
